Her heart is set on vengeance, and she now possesses all she needs to command the mighty daeva. With the help of these terrifying beasts, she can finally enact revenge against the royals who wronged her―and took the life of her one true love.But there are those who plot against her, those who would use Tea's dark power for their own nefarious ends. Because you can't kill someone who can never die...War is brewing among the kingdoms, and when dark magic is at play, no one is safe.
